fixed how templates are expanded to avoid template sub-component conflicts by changing how field keys are named. fixed various Cast functions to be more typesafe by including undefined as part of return type. overhaul of Doc.MakeClone, MakeCopy, FindRefernces - makeClone is no longer async. fixed inlined docs in text docs.
